TOOL.

Specification of Letters Patent.

Application filed May 1, 1912.

To all whom it may conce n:

Be it known that I, WASSIL SAVINKOFF, a subject of the King of England,residing at Kamsack, in the Province of Saskatchewan and Dominion ofCanada, have invented certain new and useful Improvements in Tools, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to new and useful improvements in tools and moreparticularly to tools of the wrench type, the object of the inventionbeing to provide a simple and durable tool of this character which isadapted for various applications.

Another object of the invention is to provide a tool of this characterwhich will possess advantages in points of efficiency and durability, isinexpensive of manufacture and at the same time simple in constructionand operation.

With the above and other objects in view the invention consists in thenovel features of construction and in the arrangement and combination ofparts hereinafter more fully described, pointed out in the claim, andshown in the accompanying drawings in which,

Figure 1 is a side elevation of a tool constructed in accordance with myinvention; Fig. 2 is a sectional view on the line 22 of Fig. 1; Fig. 3is a sectional view on the line 3-3 of Fig. 1; Fig. 4 is a sectionalview on the line l-4 of Fig. 1; and Fig. 5.is a detail side elevationshowing the tool adapted for use in setting tires on vehicle wheels orfor other similar purposes.

Referring more particularly to the drawings 1, indicates the shank ofthe tool which is provided at one end with the exterior threads 2, theend of the shank tapering into a point- 3 adapted for use as a screwdriver or for holding bolts while the nuts are unscrewed therefrom. Theother end of the shank is provided with a central bore 1, and having anenlarged portion 5 formed at the outer end of the shank, said enlargedportion being provided with the interior screw threads 6 adapted toco-act with the threads 7 formed on the outer surface of the thimble 8.The thimble 8 is provided on one end with an annular flange or head 9adapted to abut against the end of the shank and to limit the inwardmovement of the thimble.

Disposed within the bore 4: is the tapering shank 10 which terminates atone end into a point 11 which may be used as a punch or for prying offplow shares or for any other desired purpose. Formed on the other end ofthe shank 10 is the enlarged head 12 bifurcated at its outer end to formthe gripping jaws 13 which may be used for unscrewing pipes, nuts orvarious other similar articles. The shank 10 is provided with an annularshoulder 10 adapted to be engaged 5 and 15 each being provided with anout- 75 wardly extending arm 16, the arm on the outer sleeve 14 is to beslightly longer than the arm on the sleeve 15. A movable jaw 17 isprovided having its lower end bifurcated to form the spaced arms 18adapted to be arranged upon each side of the arm 16 formed on the sleeve15 and held securely in place by means of the removable pin 19. Anelongated slot 20 is formed in the shank of the jaw 17 and is adapted toreceive the end of the arm 16 formed on the sleeve 14, said arm beingheld securely in place by means of the removable pin 22 which isdisposed through the shank 21 and the end of the arm 16. The pins 19 and22 are held securely in place by means of the resilient retaining plate23 which is secured to the shank 21 by means of the rivet 24 which isdisposed through the shank 21 at a point in termediate of the pins 19and 22. It will be understood that the movable jaw 17 can be made of anysuitable size and any length desired. This retaining plate 23 is adaptedto swing to a transverse position as shown by the dotted lines in Fig.1, to allow the removal or insertion of the pins 19 and 22, the platebeing held in its normal position. by means of the catch pin 25 havingits end disposed in the recess 26 formed in the shank 21.

In Fig. 5 I have shown the tool so constructed that the same may be usedfor setting tires on vehicle wheels, the sleeve 14 being reversed to theopposite side of the shank of the jaw 17. The thimble 8 being removedfrom the end 5 of the shank 1, and threaded upon the pointed end 3, thehead 9 forming a flat surface adapted to be engaged against the woodfolly of the wheel to prevent injury thereto, the jaw 17 forming a hookadapted to be engaged over the edge of the tire whereby pressure uponthe opposite end of the shank will serve to force the tire upon theouter periphery of the felly.

It will be understood that this tool may be used for various otherpurposes than those heretofore set forth in the present application andit will be seen that I have provided a simple and durable tool of thewrench type which is adapted for various applications.

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope thereof.

What I claim is In a tool of the class described, the combination of ashank provided at one end with screw threads and terminating at itsextreme end in a point, spaced sleeves mounted upon the threaded end ofthe shank, outwardly extending arms formed integral with said sleeves, amovable jaw having a shank formed integral therewith said shank beingmounted upon the outer ends of said arms, removable pins disposedthrough the shank and through the outer ends of the arms, a resilientretaining plate secured at its intermediate portion to one side of the-WASSIL SAVINKOFF.
